V NITE 1): ;STATESj i -55 D, these terminals extendng'toa' suitable The intention relates-to a constructionfor rendering theffiame of a; steam `genera tor visible from the drvefis seatof anzautomobile; a

6 i The prinary object' theflnvention is toi provide a simple arrangement whereby the,

fiame is directlyivisible by the, operator ;of

a 'straight Conduit extending' fronthe driv i el` S compartnent to the po nt ad; acent the' pilot lightsothatboth thetmain burner and;

the iight niay ,be observed. A still further object is to arrange a spark plu or fother ignition means ;for the pilot. burner so that it also may be observed through the conduit. v v i These and other objects are attained by the novel constructionhereinafter fully described and illustrated in the' 'accompanying drawings Wherein 1- i f Figure 1 is a side view partly in section of a 'steam boiler and the flame sight shown in relation to the driver@ seat;

Figure 2 is a plan View of the boiler and observation tube, the former being broken away to disclose the pilot burner; Figure 3 is a longitudinal section through the pilot burner on the line 3-3 of Figure 2;

Figure 4 is a side view of a modified con- V struction.

A is a steam generator located under the hood of a steam driven automobile and provided with a burner B consisting of a perforated plate B" through whichthe fuel is v delivered from the mixer C and the inlet Conduit C'. 'D is a pilot burner fed through `40 a separate mixer D' by 'means of the inlet- Conduit D the latter being arranged to extend over the pilot burner so that 'the fuel will at all'times be preheated when the burner is in operation. As shown, this pilot burner consists of a radially extending casting E having a 'series' of parallel 'slotsE' through which the mixture is delivered.

F is a spark plug inserted in the burner casing adj acent the pilot burner D, the'plug being provided with anelectrod'e G extend--` i ing closely adjacent the side of the casting` E to form a spari: gap H therebetween.

, I and I'" arethe 'terminals connected respe`c-'` tively to the electrode G and the pilot burner source of high'tension current. V v

If for any reason, the main burner fiares blows out the'pilot burner as occasionally 'i The driver s seat is' represented bythe compartnientof theautoxnobilei; u

` lay at aiLtimesjb'e-able to ascertainl wheth-j er; jn ot the; biurner is lig-hted" there is prothe car without the necessity ;of employing' refi ectors or other indir'ect means. Another u` object -is to provide; a Construction having vided a condutK Secured to the abu'rnergcasing and ezrtending upwardly theretro'natf a e suitable' inclin ation so i that the operatori of the vehicle when in normal i position %will have clear vision throughsaid cond uitand niayi observe the flame from the; main; burne and .the :pilot burner as well as abeing able i see 'the ;spark fromthe; s'pari( plug; As shown in ;Figure1 ,.-,the;Conduit K extends; upwardly through aniaperture EL in the 'i toe` board J and is provided` at its lip-per end 'with a cap M` havinga transparent top M e a i ofglass or othr suitable material.

In the modified 'Construction as shown in i Figure i, the eonduit N extends Only a short distance from the burner caslng ands provided with a cao N'having the transparent' 0 i top piece i The toe board J `is, however,l provided with an aperture O in'alignment with the longitudnal aXis of the conduit N and preferably 'this' apertureais closed hysa glass cap P o'r othersuitable transparent covering. i v e v i v VViththe construction as above describech' the operator may. at all times directly observe .the condition of the main burner ,and the I pilot burner from the driver s seat` without m n changing from the normal driving position back during the, operation of the vehicle and happens with steam driven automobiles, the 55 driver will be 'immediately aware of that fact and may relight the pilot burner by means ofthe sparkplug F, a suitable switch iQ, being provided for that purpose; Since the spark plug is also in alignment with the conduit K the driver'wll be able to observe, v the spark i r i The arrangenent as above describedforms u a very simple means for-at all times' determining theconditiori of thejburnerand by y pla'eing the'. transparent cap for the Conduit .r i

at a suflicient distance from the fraine there will be no danger of having' it' destroyed by the heat from the burner. Thisarrangement i eliminates the use of any reflecting means i and enables thefdriver to directly observe' the flameitself. V i i What I claim as my nvention st- 1. III a steam automobil, the comhnato With a steam generator and a burner therefor, of a Conduit exterding from said generator at an inciinaton to the same, the longtudinal axis of said Conduit being a ligned With the burner and with the driver s compartment Whereby the operator' of the mitomobile may directly observe the burner fiame'. 4

2. In a' Steam automobile, the combination with a burher (jasing and a burner thereon, of a straight Conduit eXtending from said bu'rne'': c'a'sing' in ii direction to align said burnr with the eye of the autmobleoper- &tor when said operator is in norml dr`iv- 3. In a' Steam automobile', the' combination with the ffnt seat cmpartirint of an automobile' pr'vidd With fior' boards, of 21 steal-'ni grator arrnge'd 'forward f said cx' ipartm'et, a bame): in said generator, d zt vcod' it xtending from said burner toward said com artment in alg'nment with aperture in S'id floor boards, the longmdinl azis o'f said Conduit extending in a' direction to alg said burner With the eye of the autmoble driver" When said driver is innormal drving position.

4. In a steam automoble, the combnaton of a steam generato1','a main burner therefon& pilot burner, 'a spark plug adjacent said pilot bur-ner, a burner casng and a condut attache'd to said 'burner casing and eX- tending in a direction to permt direct ob Servatori 'thereth'rough from the diriver s seat of sid sprk plug, said main burner and said pilot burner;

5. In a steam automobile the combination of a, steam generator, a mam burner, a pilot bur-ner', a. s'park plug having an electrode ad j &cent said pilot burner formng a spari( gap therbetween, a burner casng, a Conduit xtendin from said burner casng at' a point &dj-&cent said s parkplug, and& transparent clos're fr said Conduit, 'said Conduit xtending in zi straight' line towards said' driver@ seat to permt direct bsrvaton f said. spark plug,` pilot burn'er and m n birrer therethrough.
